The Canadian drama series stars Caroline Dhavernas as Dr. Mary Harris, a hospital worker who has a side business as an “end-of-life counsellor” that sees she and her partner, Des Bennett (Richard Short), provide assisted suicide.

Across the series, Mary and Des are investigated by Detective Ben Wesley (Jay Ryan), who complicates business for the two entrepreneurs. The third season will pick up from last season’s shocking finale that left Ben’s fate up in the air.

Joining the cast are Canadian actresses Elizabeth Saunders (“Alias”, “Grace”) and Rachael Ancheril (“Rookie Blue”, “Wynonna Earp”). Saunders will play a nurse who causes problems for Mary, while Ancheril stars as a patient at Mary and Des’s new “death retreat”.

The official synopsis for the final season reads:

“In the third and final chapter of ‘Mary Kills People’, Dr. Mary Harris must come face-to-face with her own personal choices, ethics, and demons in a way she never has before. The death retreat is up and running, but its cover as a legitimate hospice is crumbling away and with it the idyllic vision Mary and Des had for continuing their work in quiet secrecy. With Mary’s family and the work she loves in jeopardy once more, she realizes she is finally going to have to put life, with all of its complexities and imperfections, first.”

Viewers can catch up on the first and second season of “Mary Kills People” on or Global GO (available for Apple TV, Google Chromecast, and Amazon Fire TV).

The six-part third season will air on Global in spring 2019.
